Nice stuff! I was looking around to find what else "Bill Williams" did, and this is definitely the same guy. I've seen his work on the "PEE WEE HARRIS" strip in BOYS' LIFE magazine, starting with the 5th episode (Jan'53). The strip had his signature on it, and it looked a bit better than the 4 previous episodes, all signed by "Percy K. Fitzhugh".

Credits in BL were sadly intermittent. I'm still trying to identify about 4 different artists who worked on their "Stories from the Bible" series in the mid-70s, in between Curt Swan & Frank Bolle.
